We can also identify initial and final states by finding trigger words in the language of the problem. Look for words like “first,” “initially,” or “originally” to describe initial states and “result” or “after” for final states. What volume would a sample of helium occupy at 6.0 atm if the helium was initially compressed in a 1.0 L tank at 20. atm at constant temperature? Organize your data into the table to help analyze the problem. Leave blank any boxes for which you do not have information. Drag the appropriate labels to their respective targets.arrow_forward
